The only way to get all 28 Djinn from the original Golden Sun is to use a password or to transfer your file from that game to Golden Sun 2.

Alternate music
You only just need one party member to change the music. If Felix is in the party, no matter who else is with him it will stay with his battle music. You just need Jenna in the party to hear her battle music and only Isaac to hear his version. The game chooses which music comes first if you have all three music-changing characters in the battling party. Felix's is first, Isaac's is second and Jenna's theme is last. For example, if you want to hear Isaac's or Jenna's theme, make sure they are the only music changer in the battling party.
Auto-scrolling dialogue
Holding A + B while talking to people will auto-scroll the dialogue. For example, do this at the start of the game while talking to Alex.
Blacksmith
You do not have to wait a long time for the blacksmith in Yallam to forge an item. Give him something for him to forge. Then, leave his house and the whole village. Re-enter the village immediately and go back to his house. He will have already made the item.
Character experience growth
This following is a list of characters that gain levels faster with less experience (in order): Felix, Piers, Jenna, and Sheba.

The Darkside Sword can be obtained by taking a Dark Matter to the blacksmith. It is rare to get from him, and is cursed.

Defeating Doom Dragon
Go in with the party all with levels at 45 or higher. Give whoever has the most attack points the Sol Blade. Give the Fire Brand and the Trident to the second strongest person in the party. When you go into battle, start raising the attack points with Ivan or Sheba to the two characters that have the Sol Blade and Fire Brand. Each head has about 6,000 HP. It will be a long battle, which will give it a grand total of 1,800. Keep healing your party members with Cool Aura/Pure Wish/Wish Well. When Doom Dragon casts Curse and actually gets your party member, fighting with that person until the very first flame is small. Switch with that person and continue fighting. You may want to boost your Elemental Defense or the Doom Dragon will summon some extremely strong Psynergies, such as Cruel Ruin, which can easily do 400 damage with Elemental Defense or not. It also knows Djinn Blast, which can drain all of your Djinn in your current four characters that are out. However, it will not always do just all of them. One out of two times, it gets all of your Djinn. It is recommended that you not summon anything; if you summon Charon or something similar, it will give Doom dragon the chance to end that party member. Doom Dragon will use Cruel Ruin after it loses one head, eight turns out of nine turns.
Defeating Dullahan
Dullahan has over 10,000 HP and unlimited PP. The only way to defeat him is by summoning. He recovers 200 HP each turn and can absorb your HP. Bring out three Eclipses and three Catastrophes and that should finish him. If he still is not dead, power up the party member who has the Sol Blade with a few Impacts, then deliver the final blow. Be extremely careful of the Djinn Blast.
Defeating Star Magician
Use the following trick to defeat Star Magician in Treasure Isle in about thirty to forty five minutes. Make sure you have Isaac, Jenna, Felix and Sheba/Ivan in your party. When the fight begins, have Isaac attack the balls only. Take out the refresher balls first to prevent them from healing Star Magician; then the guard balls; followed by the anger balls; and finally the thunder balls. Do not let the Star Magician to gain more than three thunder balls. Do not have Jenna attack at all. Instead, have her heal the entire party on each turn. Felix should attack (no Psynergy) the Star Magician. Sheba/Ivan should only use Psynergies to raise the party's Impact and Resistance. Concentrate mainly on the balls and not on the Star Magician. If you get to the point where there are four to five balls on the screen, then only attack them. After about a half hour, you should be able to take the Star Magician out easily due to the fact that the refresher balls were taken out first. After defeating the Star Magician you should gain 20,000 experience points.
